Hello
The power dissipation on the device will be high and you will see heating on the device. Try reducing the charge current to see if this will improve thermal rise. With 1A charge current and a 3V input to output voltage difference the power dissipation…
Hi Parthan
We do not have higher current options in the linear charger family, 1A is a max. As current gets higher the thermal management problems are more difficult.
For 2A a switching charger would be a better option.
Some to consider:
1.) BQ24133…
Part Number: BQ24005 Other Parts Discussed in Thread: BQ24004 , BQ24040 Hello,
The BQ24004/5/6 series support 2 series cells. is there an equivalent part for a 1-cell support?
Thank you,

Part Number: BQ24005 Hi all,
We are using BQ24005 to charge a 7.4V battery.
We occasionally observe charging done indication (STAT1=High, STAT2=Low) even when the battery is not fully charged.
The indication resumes back to charging (STAT1=Low,…

Part Number: BQ24005 Hi,
We are using BQ24005 for charging two pin battery.
We have set the voltage in APG/THM pin within the specified limit.
Battery charging has no issue, but without battery, the IC indicates full charge status (STATUS1 = High…

I've built a battery charger using the BQ24005 for a two-cell, 7.4V, 800maH Lithium Polymer battery
The circuit is similar to the datasheet application.
It works fine and charges the batteries, the indication…
